Prior to the event, fans can attend open workouts with the fighters Wednesday night. Doors open for the public at 5 p.m. ET at Capital One Arena. The main and co-main event fighters then will workout for fans and the media in 20-minute increments starting at 5:30.

Calvillo will go through her workout first, followed by Rozenstruik, Rodriguez and Overeem.

Unlike many UFC shows, there are no ceremonial weigh-ins for the fans Friday ahead of the event. So Wednesday’s open workout sessions are the only official opportunity for fans to see the event’s headliners before Saturday’s card.
